• The OBD test inspects the integrity and function of the DSC and outputs the results when requested by the specific tests.
• On-board diagnostic test also:
• The OBD test is divided into 3 tests:
1. Connect the WDS or equivalent to the vehicle DLC-2 connector.
2. Retrieve DTC using the WDS or equivalent.
1. After repairs have been made, perform the DTCs reading procedure.
2. Erase DTC using the WDS or equivalent.
3. Ensure that the customer's concern has been resolved.
1. Connect the WDS or equivalent to the vehicle DLC-2 connector.
2. Access and monitor PIDs using the WDS or equivalent.
1. Connect the WDS or equivalent to the vehicle DLC-2 16-pin connector.
2. Turn the ignition switch to the ON position (engine off) or start the engine.
3. Activate active command modes using the WDS or equivalent.
